M = min(A,[],dim) returns the minimum element along dimension dim. For example, if A is a matrix, then min(A,[],2) returns a column vector containing the minimum value of each row. example M = min(A,[],vecdim) returns the minimum over the dimensions specified in the vector vec...
Nonlinear programming solver. Finds the minimum of a problem specified by minxf(x) where f(x) is a function that returns a scalar. x is a vector or a matrix; see Matrix Arguments. x = fminunc(fun,x0) starts at the point x0 and attempts to find a local minimum x of the function...
min : 求最小值(minimum value) min函数主要有两种用法: 用法一:求两个矩阵对应位置元素的最小值: min(A,B)。 矩阵A和矩阵B的大小可以不一样,只要保证矩阵A和矩阵B具有兼容的大小就能够计算,MATLAB矩阵运算中支持的兼容模式会在“3.1.2算术运算”这一小节中详细介绍。 下面再举两个例子:表中第三列是运行...
(4)Create a matrix and compute the smallest element in each row A = [1.71.21.5;1.31.61.99] A = 1.7000 1.2000 1.5000 1.3000 1.6000 1.9900 M = min(A,[],2) M = 1.2000 1.3000 (5)Create a matrix A and compute the smallest elements in each column as well as the row indices of A in...
M = min(A) returns the minimum elements of an array. If A is a vector, then min(A) returns the minimum of A. If A is a matrix, then min(A) is a row vector containing the minimum value of each column of A. If A is a multidimensional array, then min(A) operates along the ...
x = ga(fun,nvars,A,b) finds a local minimum x to fun, subject to the linear inequalities A*x≤ b. ga evaluates the matrix product A*x as if x is transposed (A*x'). example x = ga(fun,nvars,A,b,Aeq,beq) finds a local minimum x to fun, subject to the linear equalities Ae...
Find the minimum of an objective function in the presence of bound constraints. The objective function is a simple algebraic function of two variables. fun = @(x)1+x(1)/(1+x(2)) - 3*x(1)*x(2) + x(2)*(1+x(1)); Look in the region where x has positive values, x(1) ...
If I want the minimum values by row in x, I can use [M I] = min(x,[],2) to obtain M = [3; 1; 2; 4] I = [1; 1; 1; 2] but I am not sure how to apply I to the y matrix to obtain y = [1; 3; 5; 8] ...
